**Part One**

In 2065, the Royce family – 14 year old Sara, 12 year old twins Katie and Ken plus their parents who are both university professors of physics – move to a small town in Nova Scotia, Canada. Sara is stunned on learning the school she’ll attend is named after Sarah Royce, a 19th century writer of local fame, whose name differs from hers by just a single letter. The kids in the school mock her, saying she came from the 19th century. A talk on time travel inspires Sara to think about this.

She discovers several Royce’s Laws on quantum mechanics, and some on time travel. The family starts working on designing a time machine, buying a Ford van and building the time travel equipment into it. They gradually invent a completely navigable time travelling vehicle, complete with the //time viewer,// a temporal camera that can look into different times.

The first manned temporal trip leads ten thousand years into the past, without mishap. But the second one happens by accident, when the parents aren’t in the //timeford,// just the kids. They go back to the 18th century, scaring a boy who was there with his sheep. They return immediately to the 21st century.

Calling their parents reveals they are at work as normal – but that can’t be the case as they went on research leave because of the time machine. But now they didn’t ever build any time machine.

We’ve changed history, Sara says.
